Sims won't sleep for more than 5 minutes

I have one plantsim and one glitched plantsim/normal sim (unrelated problem) and neither will sleep. No radio, lights anything. I'm playing with just the base game, no mods or packs. It's a room in an EA build, but none of the other beds in the house work either. It goes like this:

Send sim to bed. Sim goes to bed. Sleeps 5 in-game minutes. Wakes up. So naturally, I cue a whole bunch of 'sleep' interactions. Sim gets in bed. Sleeps 5 minutes. Wakes up for a second and goes back to bed. Repeat. Wakes up and crawls across the bed to the other side. Falls asleep for 5 minutes. Wakes up and goes back to sleep for 5 minutes. Repeat. Until I run out of cued interactions. 

I can't get their sleep bar up, so I can't play at all.

I saw someone post the same problem recently, and they fixed it by going to manage worlds and back. They slept a few hours, and then the problem returned. I've restarted the game three times, and rebooted the computer (PC). Nothing worked.

This is awful!! Please fix!
